Returning Your Old Core

At Heavy Duty Parts Company, core returns play a critical role in keeping operations efficient and product costs low for all our customers. Returning your original cylinder heads is simple and free—we include a core return label on the box, and the shipping is on us.

Our core return policy operates on an honor system, meaning we will not charge you if you don’t send back a core. However, returning cores is highly encouraged. These cores provide us with essential smaller components like springs, retainers, and keepers, which help keep our remanufacturing process sustainable and our prices competitive for everyone.

For certain cylinder heads, receiving cores back is especially valuable in helping us maintain quality and affordability across our products. If you don’t have a core to return, please reach out, and we’ll be glad to discuss alternative options. Thank you for supporting our commitment to providing quality parts at accessible prices by honoring the core return process whenever possible.
